Who needs a high dollar cold air kit

Airaid MIT for a 02 6.0 in a 2500 Sierra on my 06 Tahoe. Stock box and filter.

Outside temp was 38 so barely over a degree difference at 60.

 

I believe it was black bear that did a before and after on several cold air intakes on the dyno. Turned out a MIT tube with stock box was the best bang for the money.

Yeah, without dynoing it i wont say it added power. But it FEELS peppier.

 

Nice job. Yeah you're missing one more mod on the list, the Autocal V3 BBP tune. They can get rid of all the nannies on your truck and also get the best out of the Airaid MIT! Get a octane tune etc etc.

 

Do you have some photo's from different angles of the MIT installed on the Tahoe? Really keen to see that!! You run the 200-912?

 

Yeah ive talked to them, but i prefer to do a in person tune. My tahoe has the virtual flex sensor that reads tje O2 sensors after a fill up then adjusts timing and fuel. And ive talked to BB and several other companies including 2 local ones, most want to either disable the flex or install and actual ethanol sensor and go to an older OS. BB says they can work with it, but id like to do it in person.

 

I can try to get some later this week. I work a different schedule than my wife so i dont see the tahoe much lol

 

Cool mate, would be nice. Because the 200-912 is the mech-fan version, do you have a mech fan or e-fan?

I understand you. I first wanted in person as well. I went to a tuner who could do basicly everything that BBP can. But the difference is, BBP has sooo much experience. They really know what your stock motor and gearbox can handle, and also tune mods with it. I first really wanted a in person tune also, but this forum convinced me to go with BBP.

Why would they want to do that? So that they will tune the computer on one sort of fuel?

 

Yes its the 200-912. No mine is the efan setup, but for the price of free i wasnt going to pass up a airaid pipe.

I guess its because instead of an actual sensor reading ethanol content, the computer looks for a lean condition at the oxygen sensor. It then ASSUMES that you are running a higher ethanol level fuel so it adds timing and fuel. But if its just a gasket leak causing the lean condition, you get more timing without the added octane. So you get into danger of detonation and fragging a piston. So if you already have higher timing from a tune... you add more for what it thinks is e85 and now youre really at risk of killing the engine

 

I can imagine haha, if something like that would pass by in the Netherlands, I would buy it, although I'm going e-fan! But they say the working of 200-912 and 200-919 are the same, but the 912 is build to clear the shroud and fan. I'm just wondering if they are really identical in gains, why would you otherwise make a different one for the mech-fan and one for the e-fan.

Anyway, I'm going e-fan first before doing Airaid MIT I just decided

I also asked that question to @BlackBearPerf about a certain octane tune. Why that is necessary because the Chevy computer already does that? We only have 95 or 98 octane for example. I did a read-out at my local tuner also, he said the computer is noticing which fuel you use and will change according to that. So I'm wondering why everybody does the octane tune also?

EDIT: And I can't find out if the first gen 5.3 Vortec engines have gaskets and hoses that can handle ethanol. Since our fuel changed in 2019 in the Netherlands, there is 10% ethanol in Euro 95. I only tank Euro 98 now because that has E5 but most of the time 0% ethanol in it. We've a website to see if your car can handle it, but the American cars are not on that list... in late 2002 the flex fuel models came, so it's logical they can handle ethanol, but what about the first 5.3 vortec engines..... I think for the LS1 for example, 98 is now adviced for that car here.

EDIT2: For example BMW e36/e46 M3 should tank 98 fuel only, because those are race engines.
